金属胶具有弹性刚度低、弹性变形大、强度高、生物相容性好等特点。当它用于植入应用时，由于天然骨与人骨相比具有较高的刚性，因此仍然存在诸如超载之类的问题。因此，本研究的目的是从弹性刚度和体积密度的角度为种植体应用创造更灵活的网状板。使用三维（3D） CAD工具设计、设计和应用网格化GUM金属板的基本网格形状。对网格化GUM金属板试件的拉伸疲劳特性进行了试验评价。通过有限元法进行应力评价的分析方法，得到疲劳特性评价的SN曲线。
GUM Metal has characteristics of lower elasticity rigidity, large elastic deformation, higher strength and biocompatibility etc. When it is used for implant applications, there is still problem like overloading on the natural-bone because of its high rigidity compared with the human bones. Therefore, the purpose of this study is to create more flexible meshed plates for implant applications from the viewpoints of elastic rigidity and volume density. Basic mesh shapes are designed, devised and applied for meshed GUM Metal plates using three dimensional (3D) CAD tools. Experimental evaluation on tensile fatigue characteristics of meshed GUM Metal plate specimens are carried out. Analytical approaches on stress evaluation are also executed through finite element method to obtain the SN curve for fatigue characteristic evaluation.
